In this letter,a novel algorithm is proposed for identification of one popular type of VoIP(Voice over IP) application,MSN VoIP,based on both behavior pattern and protocol characteristics.In addition,the experiment for validation is implemented.Since there exists no method identifying MSN VoIP session and furthermore the IP addresses,domain names,ports and even the protocols MSNP works over,are all alterable during the application,which makes it difficult to identify MSN VoIP session,this work will be helpful to advance the research on VoIP identification.
